Definitions
- the invention relates to a method for producing a fracture-separated component, in particular a connecting rod, with an at least partially coated bore.
- the invention further relates to a component produced by the method.
- the object of the invention is to provide an advantageous production method for a fracture-separated component, in which it is ensured in particular in the case of a coating with a low-melting material, that after the fracture separation, the two component halves can be reassembled accurately.
- the method according to the invention for producing a fracture-separated component, in particular a connecting rod, with an at least partially coated bore comprises the following steps:
- the invention is based on the recognition that, in particular in a coating of a component with a low-melting bearing material, for. B. with a Sn-based powder, tensile stresses in the coating are induced, which lead to a "collapse" after fracture separation.
- the outer dimension (width dimension) of a bearing half is therefore smaller after the fracture separation than before the fracture separation.
- the coated connecting rod bearing cover falls over the uncoated connecting rod base due to the different stiffnesses. This undesirable effect is counteracted according to the invention in that the coating is mechanically deformed before the fracture separation of the component in order to compensate for the internal tensile stresses in the coating.
- the forming preferably includes rolling of the coating, in particular a deep rolling.
- the internal tensile stresses in the coating can be additionally counteracted by the fact that the coating is reduced to a defined extent before forming in the context of a machining intermediate machining.
- the forming can be deliberately increased to a level such that compressive residual stresses remain in the coating.
- a counter-hardening zone for generating counter-compressive stresses which are opposite to the internal tensile stresses of the coating, can additionally be formed.
- the counter-hardening zone is preferably formed before the application of the coating and preferably on an outer contour of the component.
- the size, shape and position of the counter-hardening zone can be determined experimentally.
- the tensile stresses induced in the coating that result in "collapse" after fracture separation of the component are counteracted solely by forming a counter-hardening zone prior to application of the coating.
- the counter-hardening zone generates compressive stresses in the component, which are opposite to the internal tensile stresses of the coating.
- the counter-hardening zone is preferably formed on an outer contour of the component.
- the size, shape and position of the counter-hardening zone can in turn be determined experimentally.
- the invention also relates to a component, in particular a connecting rod, produced by a method according to the invention.
- FIG. 2 is a part of a second connecting rod.
- the figures each show the large bearing eye designed as a connecting rod 10 and 20 for a motor vehicle internal combustion engine bearing component.
- the connecting rods 10, 20 are produced in a forging, sintering or sintering-forging process.
- the large bearing eye is provided with a functional support 12, 22 formed by coating its inner surface, which is based on a tin (Sn) powder.
- the function pad 12, 22 is thermally using a laser applied, so that forms a cohesive bond between the Pleuelgrundwerkstoff and the functional support 12, 22 forming bearing material.
- the functional overlay 12, 22 covers in particular all or only part of the inner bore surface of the large bearing eye.
- the functional support 12, 22 can, as shown in the figures, extend only by approximately 180 ° of the bore circumference.
- the axial extent of the radially completely circumferential or partial functional support 12 can also vary; For example, a certain axial distance from the bore edge may be provided.
- a connecting rod bearing cap 18 and 28 is separable from the big end 16 and 26 respectively.
- only the bore surface of the connecting rod bearing cap 18, 28 is coated.
- the internal tensile stresses present in the Sn-based functional support 12, 22 would lead to a collapse of the connecting rod bearing cap 18, 28 with respect to the big end 16, 26.
- the functional overlay 12, 22 is deformed before the fracture separation to compensate for the internal tensile stresses in the coating.
- the forming takes place by rolling (deep rolling, no smooth rolling), for which commercial tools can be used.
- the mechanical pre-processing required for this either represents a separate process step (turning out) or is carried out with a suitable combination tool (eg with peeling and rolling part) in the same process step.
- a suitable combination tool eg with peeling and rolling part
- this measure is combined with the formation of one or more additional counter-hardening zones 19 and 29, respectively, for generating counterpressure stresses which are opposite to the internal tensile stresses of the coating.
- the counter-hardness zones 19, 29 are formed before the application of the coating to an outer contour of the component, wherein size, shape and position of the counter-hardening zones 19, 29 are determined experimentally. Details of the preparation of the counter-hardening zones 19, 29 are explained below in the context of the second alternative method.
- the different stiffnesses of the big end 16, 26 and the connecting rod bearing cap 18, 28 are adjusted only by the fact that instead of rolling the bearing material at least one counter-hardening zone 19, 29 for generating compressive stresses is formed before the coating is applied, which are opposite to the internal tensile stresses of the subsequently produced functional overlay 12, 22.
- the counter-hardening zones 19, 29 are formed by subjecting predetermined areas of the outer contour of the component to a partial heat treatment (laser or inductive hardening). Size, shape and position of the counter-hardness zones 19, 29 and their Einhärteiefe can in turn empirically, z. B. by fracture separation of reference components without counter-hardening zones, are determined before the fracture separation. Alternatively, the bore of the component to be coated can also be wholly or partially subjected to a heat treatment (laser or inductive hardening).
- FIG. 1 shows a connecting rod 10 with a coating 12 integrated in the coating and a counter-hardening zone 19 on the connecting rod bearing cap 18 in the immediate vicinity of the bearing coating.
- the counterhardening zone 29 on the connecting rod bearing cap 28 has two extended regions 29a, 29b and is slightly spaced from the functional pad 22.
